下旋式塔式起重机,长期以来是用铁块、混凝土块等作配重的。南京市第三建筑公司设计、试制的红旗—20、红旗—30、红旗—45三种机型十台塔机中,成功地使用水作配重。经多年使用证明,水配重可以代替其它配重,且不需专门水箱,可用箱形回转平台的空腔部分来盛配重水。这样,装卸配重方便,塔机摇摆小,较受欢迎。一、水配重的特点多年来,我们用水配重的塔机施工,水配重不会发生渗漏、摇晃、冻裂和锈蚀水箱等。它与其它配重比较,具有以下一些特点: ①成本低。轻、中型下旋式塔机配重一般在10吨之内,因此,每装拆转移一次只消耗10M~3的自来水。②装卸快。盛水平台的加水、放水比较方
Down-rotating tower cranes have long used iron blocks and concrete blocks as counterweights. In the ten tower cranes of the three models Red Flag 20, Red Flag 30, and Red Flag 45 designed and manufactured by Nanjing No. 3 Construction Company, water was successfully used as the counterweight. After many years of use, the water counterweight can replace other counterweights, and there is no need for a dedicated water tank, and the hollow part of the box-shaped slewing platform can be used to distribute heavy water. In this way, the loading and unloading of the weight is convenient, and the tower crane swings less and is more popular. First, the characteristics of water counterweight For many years, we use water tower crane construction, the water counterweight does not leak, shake, crack and rust tank. Compared with other counterweights, it has the following features: 1 Low cost. The counterweight of the light and medium down-rotating tower cranes is generally within 10 tons. Therefore, only 10M~3 tap water is consumed for each transfer. 2 fast loading and unloading. Water-adding and water-discharging comparison
